Spring 踩过 websocket SubscribeMapping 不工作

Question

我正在尝试配置订阅映射，以便在 spring 引导应用程序中踩踏 websockets，但没有任何运气。我相当确定我已经正确配置了 stomp/websocket 东西，因为我能够订阅由 kafka 消费者发布的主题，但是使用 @SubscribeMapping 根本不起作用。

这是我的控制器

@Controller
class TestController {
    @SubscribeMapping("/topic/test")
    fun testMapping(): String {
        return "THIS IS A TEST"
    }
}

这是我的配置

@Configuration
@EnableWebSocketMessageBroker
@Order(Ordered.HIGHEST_PRECEDENCE + 99)
class WebSocketConfig : AbstractWebSocketMessageBrokerConfigurer() {

    override fun configureMessageBroker(config: MessageBrokerRegistry) {
        config.setApplicationDestinationPrefixes("/app", "/topic")
        config.enableSimpleBroker("/queue", "/topic")
        config.setUserDestinationPrefix("/user")
    }

    override fun registerStompEndpoints(registry:StompEndpointRegistry) {
        registry.addEndpoint("/ws").setAllowedOrigins("*")
    }

    override fun configureClientInboundChannel(registration: ChannelRegistration?) {
        registration?.setInterceptors(object: ChannelInterceptorAdapter() {
            override fun preSend(message: Message<*>, channel: MessageChannel): Message<*> {
                val accessor: StompHeaderAccessor = MessageHeaderAccessor.getAccessor(message, StompHeaderAccessor::class.java)
                if (StompCommand.CONNECT.equals(accessor.command)) {
                    Optional.ofNullable(accessor.getNativeHeader("authorization")).ifPresent {
                        val token = it[0]
                        val keyReader = KeyReader()
                        val creds = Jwts.parser().setSigningKey(keyReader.key).parseClaimsJws(token).body
                        val groups = creds.get("groups", List::class.java)
                        val authorities = groups.map { SimpleGrantedAuthority(it as String) }
                        val authResult = UsernamePasswordAuthenticationToken(creds.subject, token, authorities)
                        SecurityContextHolder.getContext().authentication = authResult
                        accessor.user = authResult
                    }
                }
                return message
            }
        })
    }
}

然后在 UI 代码中，我使用 angular 和 stompjs 包装器来订阅它，如下所示：

this.stompService.subscribe('/topic/test')
      .map(data => data.body)
      .subscribe(data => console.log(data));

像这样订阅我知道正在发送数据的主题非常有效，但订阅映射什么也不做。我还尝试在我的 websocket 配置中添加一个事件侦听器，以测试 UI 是否真的像这样向后端发送订阅事件：

    @EventListener
    fun handleSubscribeEvent(event: SessionSubscribeEvent) {
        println("Subscription event: $event")
    }

    @EventListener
    fun handleConnectEvent(event: SessionConnectEvent) {
        println("Connection event: $event")
    }

    @EventListener
    fun handleDisconnectEvent(event: SessionDisconnectEvent) {
        println("Disconnection event: $event")
    }

添加这些事件侦听器我可以看到我期望来自 UI 的所有事件都在 kotlin 层中通过，但我的控制器方法从未被调用。有什么明显的我遗漏的吗？

尝试以下操作：

@Controller
class TestController {

    @SubscribeMapping("/test")
    fun testMapping(): String {
        return "THIS IS A TEST"
    }
}
